Airworthiness Directive 2022-18-02
one-timeAirworthiness Directives; MT-Propeller Entwicklung GmbH Propellers
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain MT-Propeller Entwicklung GmbH MTV-5-1-( ), MTV-9-( ), MTV-11-( ), MTV-12-( ), MTV-14-B, MTV-14-D, MTV-15-( ), MTV-16-( ), MTV-17-( ), MTV-18-( ), MTV-20-( ), and MTV-27-( ) variable pitch propellers. This AD was prompted by reports of certain propeller blade lag screws that were manufactured with an improper surface finish, which results in reduced fatigue strength of these lag screws. This AD requires replacement of certain propeller blade lag screws with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2022-18-02 applies to
Applies only (1) to variable pitch propellers with a propeller serial number identified in MT-Propeller ASB No. 30, Revision 7, dated June 23, 2022, or (2) to those propellers with a blade bearing a serial number identified in that same ASB installed. The specific serial numbers are enumerated in the referenced ASB and not reproduced in the AD applicability text excerpt.
Whether AD 2022-18-02 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
